IMPROVED BRICK-MACHINE.

Specification forming part of vLetters Patent N0. 58,200, dated September 25, 1486 3.

To all whom 'it may concern.' v

Be it known that I, COLLINS B. BAKER, of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Brick=Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will eiia-ble others skilled in the art to make and use the same, reference being had to the accompany ing drawings,.foriniiig part of this specification, in which Figure l is a side view of my invention; Fig. 2, a plan or top view of the saine. Similar letters of reference indicate' like parts. A

This invention relates to a new and improved mechanism for striking the lled molds nthat is to say, scraping olf and leveling their upper surfaces after the molds have Y been shoved from underneath the press-box.

The object of the invention is to obtain a simple device for the purpose, and one which may be operated rapidly and in a perfect manner, the clogging of the strike, which. has a reciprocating movement, being effectually prevented and the strike only allowed to act upon the molds iii one direction, so as to scrape the superfluous clayoff from the molds at the end of the machine.

A represents the framing ot' a` brick-ma chine; B, the press-box; C, the plunger or presser, which works in the box and forces the clay into the molds E, the latter being moved under the press-box B by a roller, F, whcli works transversely over the bed G of the train ing, and is operated by arms a b connected with a rock-shaft, H, in the lower part ot the framing A, the rock-shaft beiiig moved by a handdcver, I.

i The above parts have all been previously used, and therefore do not form a part of this invention.

J represents a rockshaft which is placed transversely at the discharge-end of the inachine, and has two arms, o c, projecting from it at rightangles, said arms being slotted longitudinally and having each `a bar, d, tted in it by a pin, e.

To the outer ends of the bars d l a strike or scraper, K, is attached, which is parallel with the rock-shaft J. This scraper has a cylindrical tenori, f, formed oii each end of it, and on these tenons wheels L are placed loosely. The scraper K is of trila-teral form,

dropping upon the upper surface ot' the mold when the scraper is moved back and reaches the rear end of the mold.

At the front ends of the ways g there are diagonal or oblique bars i i, which, when the wheels reach or come in contact with them, shove the wheels L over the ways g, so that the scraper may pass back iii an elevated state over the mold.

The tenons f are made sufficiently long to admit of the wheels L moving on them the requisite distance, and on the outer or discharge end of the bed G there is a vertical fixed strip, M, a space, j, being allowed between said strip and the filled mold E. As the scraper K approaches the termination of its outward movemeut it passes over the upper edge of the strip M, and has the clay which may adhere to it scraped off, said clay falling through the space j and the clay scraped oft' from the sur-l face of the filled mold E by the scraper K during its outward movement also falls through said space. The rock-shaft J is operated by a lever, N. ,f

Thus it will be seen that the strike or scraper K, by operating the lever N, is moved back and forth and made to work over the top of the filled mold and scrape the superfluous clay therefrom during its outward movement and then cleaned bypassing over the strip M, elevated, and its wheels L shoved on the ways g g by the oblique bars t' i, so that the scraper' will be moved back in an elevated state above the filled mold, and then dropping upon the mold in consequence of the wheels L passing oif from the inner en'ds of the ways g g, the scraper being thus operated automatically by simply actuating the lever N.

1. I do not claim as new any parts pertaining to the feeding of the molds under the pressoperate in the manner, substantially as and for the purpose set forth.

2. The strip M, in combination with the scraper K, substantially as and for the purpose specified.
